@Anthony Zamora Propelio has a free academy online that has a Wholesale course. I think what you need to ask yourself is, how involved do you have to be. Wholesaling is awesome, but its also more generally ran like a business.
No matter what you do in Real Estate investing, you either need to pay in time or money. If you can only pay in time, wholesale is a great way to start building up the money for other investing strategies. It will also teach you the essentials for being successful in your endeavors, and that making your money on the buy. If you have a lot of money (or make a lot of money at another job), you have other options as well. Just depends on you.
I know for me, my wife has a pretty awesome job that pays well. We're taking her incoming and doing out of state BRRRRs. I, on the other hand, am a stay at home dad with my daughter. I decided to get into wholesaling so that we could accelerate our growth. My plan is to take some time making money while learning how to find the best deals. From. There, I will start flipping, then I will get into other strategies as well. In a sense, I'm treating it like a building block to long term success.
You should take a weekend to really think of what you want your goals to be. Do you want to be more passive? If so, how can you invest while being more hands off? Do you put in some time? Buy turnkey? Become a private lender or equity partner with someone who has time?
Or, do you want to be more hands on and use less money? If so, how do you build your skillset? What do you need to educate yourself on? How will this build into long term wealth?
